'Application filed January 27, 1909. Serial No. 474,360.

To oZZ whom it may concern:

n Be it known that I, ISAAC Snow, a citizen of the United States,residing in Lawrence,

lin the county of Essex and State of `Massa- `thei'ollowing is aspecification.

This invention relates to shuttles provided with threading-devicesmaking a part 'thereof, and consists in a construction by means of whichthe thread is guided to the threadhole or eye without the employment ofa slot or slit .in the wall of the shuttle coiniecting with said eye,guarded from unthreading,

loopingup, floating, breaking, and getting out of place, kept down onits way through the passage leading to the eye, and the necessity yforblowing the thread in order to' place it into land through the eye isobviated.

The nature of the invention is fully described in detail below, andillustrated in the accompanying drawings, in which Figure l is a planview of a shuttle ein.`

bodying my invention, the thread being in position and extending throughthe wall thereof. Fig. 2 is an enlarged detail, partly in longitudinalvertical section and `partly in elevation of the head -oi theshuttle,show ing the location and shape of my improved plate. Fig. 3 isan enlarged View partly in plan and partly in horizontal section of thesame. Fig. l is a vertical section taken on llne-fl, lFlg. 3.

a represents the front Wall and Z2 the head of a shuttle embodying andprovided with my invention, c is` the bobbin sustained by a suitablespindle and al the thread extending 'from said bobbin, the position ofsaid thread while it is passing from the bobbin to and through the eyebeing illustrated in Figs. 1 and 3. y

Secured inf a slight recess c in the inner end of the head Z) isan openring or coil f, the passage g in said ring or coil being illustrated inFigs. 3 and4. This ring may be secured in any desired manner, the meanslllustrated conslsting of an integral spike /t Vwhich is drivenhorizontally into said end at f the recessed portion c. Connecting withthis recess is a deep vertical passage 7c' longitudinal with theshuttle, whichextends between the head oit the shuttle and the verticalwall Z substantially V-shaped in vertical section '(Fig. et) andtapering toward its outer end, said wall being integra-l with the headof the shuttle und extending uptherei L;

from, and connecting with the wall u of the shuttle by the neck portionz'. This wall Z separates the longitudinal rear passage 7c frein avertical passage m which extends in front of said wall, and the passagesc and 15g m haveinelined bottoms which extend up` ward to\\and meet at atapered groove 'n longitudinal with the sluttle 'and extending from theconvergingy passages toward the extreme end of the shuttlesaid taperedgroove also havingan inclined bottom (Figs.V 2 and 3). The two assages Zand fm, are connected by `a horizontal cross passage ,0, open at itsupper end',`,and the passage m is furthermore connected' by a horizontalhole p with the outside of the shuttle, said hole extending through thefront wall a and 'opening into said passage ma" It will be noticedbyreference to Figsfland 3 that the bottom Aportion m of Athe passage min- 1' clines or curves downward and rearward to the hole j), and fromthe other or rearside of said hole its bottom .e inclines upward andconnects with the interior of the shuttle.

.Screwed at g to the upper end of the wall Z and at y' to the' bottom ofthe cross passage 0 is a plate which comprises the horizontal4 taperedtop rwhich rests on the top of the partition wall Z, a side wall sextending down -centrally at a general angle in the passage. m andprovided with a horizontal groove t on its outer surface formed bybending said` I.

portion s inward, and an extension at its lower end which consists of atongue u whose outer edge is .circular and whose inner edge isconcentric with the outer edge, the eX- treme end ol said tongue beingformed up into a vertical guide v preferably beveled at its upper end,see Figs. 2 and l-Figill showing the bevel. This tongue thus pro-v ducesa thread-hole or eye 'w and when the plate is in position the tongueportion with its central eye is in or nextthe hole p, or,

more strictly speaking, is' at the point where Just opi said hole joinsthe m.

posite the inneredge o'l the extension or' guideeportion u of .thetongue' the portion S of the plate'is formed into a distinct shoul-' lder y, as illustrated particularly in Figs. l and 5.

, into and'through the thread-hole `or eye w vdrawn through the openring or coil f then along tne passage c between the walls To thread theshuttle, the thread is irsgl;

thereof and the adjacent edge of the top r and beyond said edge alongthe connecting groove a. lt is then drawn back under the left outerendor tip of said portion '11 and into the passage m between the outerwall of said passage and the side wa'll s of the plate vand along thegroove t on the outer surface of said side wall s, the pull being ofcourse r inward or toward the bobbin. As the pull Aon the thread iscontinuedit'is drawn or falls -downinto the cross passage Q and behindthe beveled upper end of the guide fv, and -is drawn down betweenthetongue u and the portion s and under the shoulder y and thence alongand across the-outer side ot the tongue u up the inclined bottom e oftheinner end of the passage m'into the shuttle. The-portion of thethreadv which is thus brought into-sight through the hole p on he outersurface/of the tongue 4u isthen gras ed without diiiiculty and withoutany necessityof blowing, and as much of the thread as desired may bedrawn out through the eyefw. Thus the thread is elfectuajlly guided andguarded Vfrom unthreading, prevented from looping up or floating-,Wandkept down on its Way through the passages leading to the eye, and isgrasped without,

any necessity for blowing. it into an accessible position.
